I made cupcakes using a tip for a rose on top. I also made butterflies out of royal icing and placed them on top of the cupcakes, but after an hour the butterflies went soft. Can you please tell me why this has happened?

Royal icing decorations need to dry for at least 24 hours before placing on top of buttercream or fondant. Make sure that they have completely dried next time before adding them to your creations.
